(1) Waterproof and moisture-proof: do not use chargers near water sources such as bathtubs, washbasins, or wet basements.

(2) Anti-cold heat release: High temperature will shorten the life of electronic devices, deformation or melting of plastic parts. Undercooling will cause moisture to form inside the charger and damage the circuit board

(3) anti-fall and shock-proof: damage to electronic components will burn the circuit board, and damage to the shell has the risk of electric shock. Do not plug and remove the charger with wet hands, otherwise it may cause electric shock injury.

(4) Anti-strong chemicals: do not use strong chemicals, cleaning agents or strong detergents to clean the charger. In addition to the appearance of the charger stains can be cotton with a small amount of anhydrous alcohol scrub.

(5) Discharge static electricity during cleaning: clean the charger and charging interface regularly. When cleaning, use a damp cloth, or an antistatic cloth. Do not use dry cloth! Accidentally landed in the process. Do not drop, tap, or vibrate the charger. Handling the charger roughly will destroy the internal circuit board.

The case of fire caused by inferior power adapter is very common in real life, most people hear similar news will complain about unscrupulous power adapter manufacturers inferior products harm people, power adapter factory that the factors leading to fire power adapter is a large part, but the user's improper use is also the direct cause of fire Z, Because most of the inferior power adapters are unreasonable in the design scheme and cut corners in the specific production process, but the basic function of Z still has a certain guarantee of safety, although this guarantee Z is not up to the national standard, but if the user uses it according to the normal use specifications, there will be basically no problems. It is precisely because the user has taken abnormal means of use, which directly leads to the problem of this power adapter that is not very good in design.
